No, it is not. This problem will solve itself with time. Many players have several dozens of vehicles in their Garages, so they don’t have enough Spare Parts for the entire vehicle fleet. But you will gradually collect enough Spare Parts to unlock new slots for purchased tanks in time.

As WG sees fit. They add a nation and line here and there as an incremental update as part of keeping it interesting and give people something to grind for and spend gold, freexp, money, ...

Do most players care?

No. The excitement for grinding new tanks is at an all time low with veterans and previously motivated players. People only have / had spare parts for 10% of the tanks they own, if they have an expanded garage ( if you have only ten tanks but played over a hundred, trading up etc then no issue) ... and they don't want to drive / grind stock.

The high tier Swedish heavies have crazy strong turrets and great gun depression. Personally I hate facing them in WoT when driven by a good player. They do have a slower ROF than the other heavy auto-loaders but that doesn't really help when you can't pen them when hull down.

Yeah, On PC PS4/XBOX version the swedish tank are BEASTS and power houses.I hate to go face-to-face with one with another tank

Sweden was neutral in WW2 and at most only passively supported Nazi Germany. Hermann Goering's wife was Swedish, FWIW.

I may need to look it up, but I don't think Sweden has fought in a war since Napoleonic times.

This does not mean they did not develop tanks. To this day, the Swedish army has main battle tanks, just like everyone else. They have settled on the S-tank, which is extremely unique with its pneumatics and turretless design. Why must a country not have tanks if they are neutral? If you dont believe me, look up arsenalen. Or the S-tank, for that matter. The Sweds have been making quality furniture and tanks throughout the 20th and 21st centuries.
